Adjustable support for an LCD monitor
Abstract
An adjustable support for an LCD monitor has a base plate. An
inverted U-shape base seat is mounted on the base plate and has a
first aperture defined through an upper wall thereof and a first
stop formed on the upper wall. A vertical axle is pivotally mounted
on the base seat. The axle has a threaded part extending through
the first aperture and a spacing collar on the first aperture, and
is engaged with a first nut beneath the upper wall of the base
seat. The spacing collar has a notch defined at an outer periphery
thereof and the first stop is located within the notch. Two ears
are oppositely formed at an upper seat on a top end of the axle,
wherein each of the ears has a cutout defined at a front end
thereof. A monitor bracket has two fingers respectively pivotally
mounted on the ears and each with a second stop formed thereon and
limited by the cutout when the bracket is turned relative to the
ears.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to an adjustable support for an
LCD monitor, and more particularly to a support which can be turned
about both a horizontal axis and a vertical axis.
2. Description of Related Art
LCD monitors as computer peripheral equipment are welcome because
of being light-weight and having excellent display quality. A
conventional support for the LCD monitor only can be adjusted about
a horizontal axis and so the LCD monitor only can be turned up or
down. When required to be turned left or right, the LCD monitor and
the support must be lifted up and turned, which is clearly very
inconvenient for a user.
Therefore, the invention provides an adjustable support for an LCD
monitor to mitigate and/or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a support
for an LCD monitor which can be turned about both a horizontal axis
or a vertical axis.
Another objective of the present invention is to provide a support
for an LCD monitor which can be securely positioned in a desired
direction when adjustment turning has stopped.
Other objects, advantages and novel features of the invention will
become more apparent from the following detailed description when
taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of an adjustable support in accordance
with the invention mounted on an LCD monitor;
FIG. 2 is an exploded perspective view of the adjustable support in
accordance with the invention;
FIG. 3 is side view of the support being turned about a horizontal
axis; and
FIG. 4 is a top view of the support being turned about a vertical
axis.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, a support in accordance with the
present invention comprises a base plate (10), a base seat (20), a
vertical axis assembly (30), and a monitor bracket (40) for an LCD
monitor (50) to be mounted thereon.
The base support (20) mounted on the base plate (10) is formed as
an inverted U-shape with two side walls and an upper wall. A first
aperture (21) is defined through the upper wall of the bracket
(20). A first stop (22) is formed on the upper wall and beside the
first aperture (21).
An inverted L-shape arm (23) is formed with an upright plate and a
lateral plate. The upright plate of the arm (23) is mounted on a
side wall of the bracket (20), and a second aperture (24) defined
through the lateral plate is in alignment with the first aperture
(21).
The vertical axis assembly (30) is composed of an axle and an upper
seat (31) formed on an upper end of the axle. Two ears (not
numbered) are oppositely formed on the upper seat (31), and two
first holes (32) are respectively defined through the ears (31).
The ears each have a cutout (33) defined at a front end thereof.
The axle extends through the second aperture (24) and has a
threaded part (303) formed at a lower end thereof and extending
through the first aperture (21). The threaded part (303) has two
first flats (not numbered) diametrically oppositely defined on an
outer periphery thereof. A spacing collar (301) is provided on the
upper wall of the base seat (20) and has an opening formed as a
configuration corresponding to the cross section of the threaded
part (303) for the threaded part (303) extending therethrough and a
notch (302) defined at an outer periphery thereof. The first stop
(22) is located within the notch (302) to limit a turning extent of
the vertical axis assembly (30).
The threaded part (303) is engaged with a nut (307) under the upper
wall. A first washer (304), a plurality of friction rings (305) and
a second washer (306) are in turn provided between the upper wall
and the nut (307) to increase the friction to the axle for securely
positioning the axle at a desired direction when its adjustment
turning is stopped. The second washer (306) also has an opening
formed corresponding to the cross section of the threaded part
(303).
The monitor bracket (40) has two fingers (41) extending rearwards
and each has a second hole (42) defined therethrough. Two second
stops (43) are respectively formed on the fingers (41). Two screws
(44), each with two flats diametrical oppositely defined at an
outer periphery thereof, are respectively inserted through the
first and second holes (32, 42) to pivotally mount the monitor
bracket (40) on the upper seat (31) of the vertical axis assembly
(30). The first holes (32) are each formed as a configuration
corresponding to a cross-section of the screws (44). The cutouts
(33) match the second stops (43) to limit the turning extent of the
monitor bracket (40).
Two third washers (45) are respectively provided between the screws
(44) and the fingers (41). The screws (44) are respectively engaged
with second nuts (48) between the fingers (41). A fourth washer
(47), and a plurality of second friction rings (46) are in turn
provided between each of the nuts (48) and the fingers (41) to
increase the friction to the respective screw (44) for securely
positioning the support at a desired direction when adjustment
turning is stopped. The fourth washers (47) each have an opening
formed as a configuration corresponding to the cross section of the
screws (44).
According to the present invention, the LCD monitor (50) can be
adjusted up or down by turning the monitor bracket (40), as shown
in FIG. 3; and can be adjusted left or right by turning the
vertical axis assembly (30), as shown in FIG. 4.
It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
